i was on a family day out on a steam train and on the way home an infirm old man got on with his carer. she left shortly after and he was on his own in his wheelchair with me and my dh and dc's. this journey was about an hour long and ds being cranky started to cry. and the old man turned to him and shouted at him to be quiet boy. at this i told him to shut the fuck up and a list of words i cant mention here. dh backed me up although i was telling a friend later she said he was ok too this as he was old, we are now not speaking cause of this. AIBU for doing that to an elderly person.
